To all whom/it may concern: [which is guided through an a erture 8 in a Be it known that I, ROBERT S.

An arcuate duct When the cars equipped with the memor passage 6 extends from the ocket 2 to the bers of the improved coupling or connecting front end of the body 1, the orward end of device come together, the nipple 7 of each rio 5 5 said duct beinor threaded for the ladjustment member will be guided; by the funnel 4 into Y therein of a orwardly extending nipple 7 the pocket 2 of the mating member, the elasto the pocke mounted in the forward end of the pocketv tic Washers 5 servin to prevent leakage of n and having a laterally extending apertured air around the nipp es. .Each nipple 7, on entering the pocket 2 of the mating member of the coupling device will displace the spring actuated valve i9 by engagement with the anti-friction roller 25, thus openinor the port 18 to the' passage of air which will then be free to pass through the nipple 7 and duct 6 t 2 and ort 18 of the mating member, thus establis 'ng the desired comrnunica'tion. i When the cars arev separated, the ports 18 will be instantly and automaticf ally closed by the action of thev s rings 21; 'the tendency of the air pressure, W en in excess, bein to seat the valves more firmly.

From t e foregoing description taken in connection Wit the drawings hereto anneXed, the operation and advantages of this invention" will be readily understood by those skilled in the art to which it apper tains The construction of theY improved air coupling is very simple, and its operation is at all times certain, and thoroughly effective. It is moreover entirely automatic in its operation, and the traincrew will not have to be depended upon to. operate air cups and other connections.

Having thus fully described the invention, what I claim as new is z l. In an air pipelcoupling a pivotally suported body member, a tension spring engaging the', same to take up slack upon the pivotal supporting member, a hanger disposed the body member, and a spring l the hanger with the body member 'j latter in proper alinementfor l tween said ward end of the duct and guided through the apertured flange.

4. In an air pipe coupling a body member having a. longitudinal pocket and a lateral duct connecting the pocket with the forward end of the body member, a funnel shaped guide at the forward end of the pocket, an air ipe openinginto ody member adjacent yto the inner end of the pocket, and communicating therewithr` through a port or passage, l ated valve seated uponsaid port or passage I andhaving an engaging member projecting therethrough.
